So, I finally found my 2500 Avalanche, Loaded 2002 95,000 miles, leather sunroof, heated seats, 8.1L. 3.73:1
What is the best way to level the front end? Torsion cams, spring spacers or coiled shocks? I have been on the truck forums no one seems to agree over there.

Also, I have a friend that has a set of 2" wheel spacers that he will give me but they are aluminum not steel. They are used; When I indicate them they are concentric and seem to have no issues. Opinions?

how much does it need to come up ? you can get it up a good bit by cranking up the adjusters, jack it up 1st to take some load off, lube the bolts, long breaker bar 18mm socket most you can get close to 2" out of, alignment needed after

I had a Avalanche 2500. I recommend "keys" for the front to level. Cranking the torsion rides hard. I have aluminum spacers. I really didn't notice much difference with them on. I had 137k on mine. I did a Hypettech tuner and it really helped performance, gave me another 500 rpms on the 8.1 and you need it when towing.

I also replaced the shocks with new Bilsteins at 110k and wow- really helped.

Check out truck and van specialist between zeeland and Hudsonville on Chicago drive they will take good care of you. I have used them a few times, they did a leveling kit for the last 3500 I had and I plan to bring them my last dually I just got.

I would go with new keys for anything more than 1/2" of front end lift. The aluminum spacers should be fine, but you will see a much better overall towing stability increase if you dump those factory pizza cutter wheels/tires. Maybe keep them for winter, but go to an 8" or 9" wide wheel for summer/towing.

I put up a lot of posts years ago on mods to my Avalanche 2500.

I prefer the DiabloSport PowerTuner over HyperTech now. I've had both.

Also, you need to dump that factory hitch. It's garbage. Go to a true Class-V hitch and you will be golden.

This should fit it:

I had a Curt hitch on mine. They are out of business now, but used to make a fantastic product.

I've been through your post. That is a lot of the reason I went with the Avalanche 2500.
I am kind of surprised with the mileage I have seen. On my trip home 176 miles; 112 miles at ~60 mph Highways and 64 miles at 72 mph Expressway = 16.07 mpg and the last 209 miles daily driving, city, highway and towing the Scarab 30 miles = 12.77 mpg. I do drive with a light foot. I did see 9.97 mpg with 143 miles city and little highway driving, expected. This is all hand calculations.

I just bought a Curt for my Cadillac STS so I can put my bike rack on my car.

Thanks everyone, I think I'm going to buy this kit and have my brothers shop install it. Then I will get the new rims and tires. I plan on keeping this for a while.

For the leveling it, get new torsion keys. If you just crank them, it will eat tires even with being aligned.

I just got a new Curt hitch this Spring rated at 16k for my 2500HD. Eastern Marine was cheapest by far and it was drop shipped free.

raisint the front end your going to find that the rear will now sag..i do the shocks and keys,,have them ship you the longer shocks for the rear and add a leaf..it will handle the tongue weight better as well. it will raise the ass 2 ''

too bad you found one, I just put my 03 2500 AVY up for sale this weekend!

FWIW I have a 2" torsion key leveling kit in mine and it worked perfectly. I would never just crank the bars to get more lift without keys, did that once on different truck and rode like crap. I did the 2.5" front keys with shock extender brackets and 1" block in the back.

If you are interested, I have a brand new in box Trailmaster 4" (Bought out BDS) suspension system for the 2500 AV/Burbs that I am selling as well. Full drop knuckle kit with shocks $1250 all stamped "Made in USA." I also have the Cognito upper control arms new in box with ball joints for another $500. This combo would give you a mid-travel suspension kit with improved geometry. PM me if you are interested.
